And the pig, though it has a divided hoof, does not chew the cud; it is unclean for you. You must not eat their meat or touch their carcasses; they are unclean for you. Leviticus 11:7-8

Answer.....
Lev 5:1-5

Quote:

" 'If anyone sins because they do not speak up when they hear a public charge to testify regarding something they have seen or learned about, they will be held responsible. 'If anyone becomes aware that they are guilty—if they unwittingly touch anything ceremonially unclean (whether the carcass of an unclean animal, wild or domestic, or of any unclean creature that moves along the ground) and they are unaware that they have become unclean, but then they come to realize their guilt; or if they touch human uncleanness (anything that would make them unclean) even though they are unaware of it, but then they learn of it and realize their guilt; or if anyone thoughtlessly takes an oath to do anything, whether good or evil (in any matter one might carelessly swear about) even though they are unaware of it, but then they learn of it and realize their guilt when anyone becomes aware that they are guilty in any of these matters, they must confess in what way they have sinned. As a penalty for the sin they have committed, they must bring to the LORD a female lamb or goat from the flock as a sin offering [fn]; and the priest shall make atonement for them for their sin.

When a sin offering was made the animal was sacrificed as the replacement for the person. They would place their hand on the head of the animal and that would transfer the sin to the animal. This is also known as Atonement.

Answer.......
Leviticus 18:3-5

Quote:

You must not do as they do in Egypt, where you used to live, and you must not do as they do in the land of Canaan, where I am bringing you. Do not follow their practices. You must obey my laws and be careful to follow my decrees. I am the LORD your God. Keep my decrees and laws, for the person who obeys them will live by them. I am the LORD.

Oh look, there is context! God didn't want them to act like other people because God knew his people would fall into the temptation that came from those cultures. I suppose you could argue that we shouldn't have long hair, but then we get into the trumping discussion that Paul has in the NT about being "every thing to every man". 1 Corinthians 9
